Banana tomato cultivation techniques

Banana tomato cultivation techniques

Banana tomato is a new tomato hybrid introduced from the Netherlands. It is named because it resembles a banana. This species is early mature, strong growth potential, plant height up to 1.5 meters, the top of the fruit is wide, 16-18 cm long, 3-4 cm in diameter, slightly green shoulders, skin thickness is easy to peel, color, flavor is superb, has great The promotion value. Cultivation methods Banana tomatoes can be grown in greenhouses, spring-autumn greenhouses, and large arch sheds. Generally, they can be planted in greenhouses in mid-December and planted in mid-February to mid-March. The open field cultivation can be planted in Yangshuo from late January to early February and planted in the middle of April. Seeding nursery 1, pre-planting preparation can be used 10 cm 10 cm nutrition seedlings or block seedlings. Bed soil is prepared according to the ratio of 7:3 of Datian soil and high-quality manure, and 1.5 kg of nitrogen, phosphorus and potassium ternary compound fertilizer is added to 1 cubic meter of bed soil after sieving, and 10 kg of plant ash is added. After mixing, it is filled into the seedbed or the nutrient solution is ready for broadcasting. . Seed treatment soaked with warm water at 55°C for 15 minutes before sowing, then wrapped with clean wet gauze, placed in 25-30°C environment to germinate, most of the seeds can be sown after dew. Seed sowing seedbed or nutrient soaked first water, water infiltration after each point into a seed, or seedbed by 10 cm square block, in the middle of the nutrition box into a seed, after 1.5 cm cover soil. Before the emergence of the bed temperature 28-30 °C during the day, 18-20 °C at night is appropriate, after the emergence of seedlings to maintain the temperature of about 26 °C, night temperature 12-15 °C. The greenhouse nursery is about 60 days, Yangshuo nurses about 80 days, until the seedlings grow to the first inflorescence when budding can be planted. Soil fertigation, suitable for planting banana tomatoes should be selected for deep soil and loamy soil with rich organic matter. 15,000 hectares of high-quality soil-fertilizer before 1/15 hectares of cultivation, 100 kg of superphosphate and 30 kg of potassium sulfate were planted in the protected land. After fertilization, the soil was ploughed and flattened and ridged in a size of 70 cm and 50 cm. When the planting time is selected, it should be carried out in the sunny morning, planted at a spacing of 28 cm, and cast enough water to avoid pouring water to reduce the temperature and affect the seedlings. After the planting, management 1, after the cultivation of the planting planting, the shallow cultivator will be carried out from shallow to deep, the topsoil will be smashed loosely to store water, protect the earthworms, increase the temperature, promote the deep roots and leaves of bananas and tomatoes, and enhance plant resistance and load resistance. Fruit ability. Before planting fruit, it usually takes 3-4 times. 2, the plant to adjust the growth of banana tomato strong, production is not easy to cause falling flowers. To adjust the balance between vegetative and reproductive growth and improve light and microclimate conditions in the field, plant adjustments must be made. Single stem pruning is adopted, that is, only the main stem is retained and all other lateral branches are removed. In the greenhouse and spring and autumn shed cultivation, hanging vines are planted; scaffolds can be cultivated in large arch sheds; uncovered cultivation is generally carried out when the plants are planted in open fields, and the main stalks are topped with 2-3 spikes. 3. The planting of preserved fruits and fruits in protected areas will cause relatively large temperature changes due to low ground temperature, affecting inflorescences and fruit setting. In the initial stage of flower development, 15-20 mg/kg of 2.4-D or 25-30 mg/kg of rhodamine can be used to decorate or daub a flower stalk. In the open cultivation of banana tomatoes, the concentration of applied plant hormones can be appropriately reduced. 4. Management of fertilizer and water After the banana tomato in early spring enters the fruiting period, the amount of fertilizer needed to increase can be 15 kg of 1/15 hectares of urea and 20 kg of fruit and vegetable-specific compound fertilizer after sitting on the 1st ear, and then watered. After 3 weeks, you can chase the fertilizer once and keep the soil moist to promote fruit enlargement. 5. Diseases and Insect Pests The common diseases of banana tomato are late blight and gray mold, which are very harmful to fruits and leaves. Control methods: (1) Strengthen field management and properly reduce the air humidity in the field. (2) Central diseased plants were detected in time, and special effects agents were used for prevention and treatment. Late blight can be controlled by using 72% DuPont Kelu wettable powder 500 times, once in 7 days, and spray 2 - 3 times. Gray mold can be sprayed with 25% Pratt & Poor WP 800-1000 times to prevent and cure, 7-10 days 1 time, once every 3 to 4 times. 6. Timely harvested banana tomatoes are higher in sugar content than normal tomatoes, and have a green shoulder when mature, which can be harvested when they are ripe. Harvesting should be conducted in the afternoon, and most of the whole fruit can be harvested and listed at one time.
